Hi,

Run environment: ArchLinux Python 3.8.6 virtualenv setup.

It install flawlessly, connects and identifies the course/s available no problem. When it starts the download I get:

[*] : Downloading accessible courses information .. (done)
[1] : Programming Use Cases with Python 
[?] : select course number or range (1/1/range): 1

[*] : Course 'Programming Use Cases with Python'.
